-
The following core services need to be running for the demo:
- ipld-eth-db
- Version: v4.2.3-alpha
- geth
- State diffing service should use
ipld-eth-db
for database. - Version: v1.10.26-statediff-4.2.2-alpha
- Endpoint: http://127.0.0.1:8545
- State diffing service should use
- ipld-eth-server
- Should use
ipld-eth-db
for database. - Version: v4.2.3-alpha
- Endpoints:
- Should use
- ipld-eth-db
-
Create a postgres12 database for the watcher:
sudo su - postgres # If database already exists # dropdb mobymask-watcher createdb mobymask-watcher
-
Create database for the job queue and enable the
pgcrypto
extension on them (https://github.com/timgit/pg-boss/blob/master/docs/usage.md#intro):# If database already exists # dropdb mobymask-watcher-job-queue createdb mobymask-watcher-job-queue
postgres@tesla:~$ psql -U postgres -h localhost mobymask-watcher-job-queue Password for user postgres: psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1)) SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off) Type "help" for help. mobymask-watcher-job-queue=# CREATE EXTENSION pgcrypto; CREATE EXTENSION mobymask-watcher-job-queue=# exit
-
In the config file update the
database
connection settings. -
In
watcher-ts
repo, follow the instructions in Setup for installing and building packages.# After setup yarn && yarn build
-
Run the job-runner:
yarn job-runner
-
Change directory to
packages/mobymask-watcher/
and run the watcher:yarn server
-
Clone the MobyMask repo.
-
Checkout to the branch with changes for using this watcher:
# In MobyMask repo. git checkout use-laconic-watcher-as-hosted-index
-
Run yarn to install the packages
yarn
-
Deploy the contract:
cd packages/hardhat yarn deploy # deploying "PhisherRegistry" (tx: 0xaebeb2e883ece1f679304ec46f5dc61ca74f9e168427268a7dfa8802195b8de0)...: deployed at <MOBY_ADDRESS> with 2306221 gas # $ hardhat run scripts/publish.js # ✅ Published contracts to the subgraph package. # Done in 14.28s.
Export the address of the deployed contract to a shell variable for later use:
export MOBY_ADDRESS="<MOBY_ADDRESS>"
-
Run the following GQL mutation in watcher GraphQL endpoint http://127.0.0.1:3010/graphql
mutation { watchContract( address: "MOBY_ADDRESS" kind: "PhisherRegistry" checkpoint: true ) }
-
Get the latest block
query { latestBlock { hash number } }
-
Run the following GQL query in GraphQL endpoint
query { isPhisher( blockHash: "LATEST_BLOCK_HASH" contractAddress: "MOBY_ADDRESS" key0: "TWT:phishername" ) { value proof { data } } isMember( blockHash: "LATEST_BLOCK_HASH" contractAddress: "MOBY_ADDRESS" key0: "TWT:membername" ) { value proof { data } } }
-
Run the following GQL subscription in generated watcher GraphQL endpoint:
subscription { onEvent { event { __typename ... on PhisherStatusUpdatedEvent { entity isPhisher }, ... on MemberStatusUpdatedEvent { entity isMember } }, block { number hash } } }
-
Update isPhiser and isMember lists with names
yarn claimPhisher --contract $MOBY_ADDRESS --name phisherName
yarn claimMember --contract $MOBY_ADDRESS --name memberName
-
The events should be visible in the subscription at GQL endpoint. Note down the event blockHash from result.
-
The isMember and isPhisher lists should be indexed. Check the database (mobymask-watcher) tables
is_phisher
andis_member
, there should be entries at the event blockHash and the value should be true. The data is indexed inhandleEvent
method in the hooks file. -
Update the the previous query with event blockHash and check isPhisher and isMember in GraphQL playground
query { isPhisher( blockHash: "EVENT_BLOCK_HASH" contractAddress: "MOBY_ADDRESS", key0: "TWT:phishername" ) { value proof { data } } isMember( blockHash: "EVENT_BLOCK_HASH" contractAddress: "MOBY_ADDRESS", key0: "TWT:membername" ) { value proof { data } } }
The data is fetched from watcher database as it is already indexed.
